Celtics win record-breaking 18th NBA title with Game 5 victory over Mavericks

Jayson Tatum put his hands behind his head, with TD Garden fans standing on their feet cheering around him, and took it all in.

Walking to the bench, he wrapped both arms around Celtics coach Joe Mazzulla.

The journey was complete.

The Boston Celtics again stand alone among NBA champions.

Tatum had 31 points, 11 assists and eight rebounds, and the Celtics topped the Dallas Mavericks 106-88 on Monday night to win the franchise's 18th championship, breaking a tie with the Los Angeles Lakers for the most in league history.
